Filter by:The purpose of this study is to determine if brief sounds or tones presented within a restricted period of recovery sleep after a period of sleep deprivation will enhance restorative properties and improve performance during a subsequent period of wakefulness.
The COVID-19 pandemic and social isolation order induced stress/anxiety as well as cellphone dependence. As a result, sleep disruption and mental distress became major health concerns. Gamma-aminobutyric acid type-A receptor (GABAAR) is one of the key players in modulating sleep. Dihydromyricetin (DHM), an herbal compound, plays a role in GABAAR modulation and mitigating anxiety. The investigators' partner in China obtained 288 participants who completed the online survey to gain insight into how stress/anxiety and time spent on cellphones affected sleep and mood. The participants were then enrolled in a randomized placebo-controlled double-blind study to assess the effects of DHM on sleep and improvement on stress/anxiety and cellphone using time.
Nocturia is the leading cause of sleep disruption with its subsequent negative impact on general health and QoL for a large proportion of the adult population. Nocturia is prevalent in men and women of all ages but may be particularly bothersome in younger adults, in whom the consequences of sleep disturbance may be more detrimental for daytime functioning and possibly for health and mortality.The underlying causes of nocturia obviously influence the efficacy of different treatment options. Because a major cause of nocturia is overproduction of urine at night, nocturia may not respond to treatments designed to reduce urgency and increase bladder capacity or increase urine flow, such as agents for the management of bladder outlet obstruction.
Many people are required to work in stressful situations combining sleep debt and hot environmental conditions. If the effect of sleep debt on cognitive performance is proven, this effect could be increased, during heat exposure, through the deleterious effects of sleep debt on thermoregulatory abilities. These alterations may favour the occurrence of accidents. The changes in cognitive performance induced by hyperthermia are also poorly characterised and often not dissociated from the effects of dehydration. Little is known about the effects of the combination of sleep debt and heat exposure on mental performance. Describing and understanding the alterations induced by this combined situation could provide a better understanding of the mechanisms explaining the deterioration of performance in hot conditions and promote the development of appropriate countermeasures.
Sleepiness caused by sleep deprivation may increase the risk of injuries and damages during physical activity. Individual data so far indicates worsening of postural stability and control with females exhibiting better static postural stability regardless of sleeping conditions in comparison to men. However, the literature is deficient in terms of postural stability conditions with eyes open and eyes closed states, as well as fall risk and sensory integration of balance.
The project will contribute with new knowledge concerning how short rest periods between two consecutive shifts (<11h, often defined as a Quick Return (QR)) affects sleep and cognitive performance. The study will further examine whether individual differences in personality traits and genotypes may explain individual differences in performance and sleep. Data will be collected with a randomized cross-over design, in an experimental laboratory setting.
This research study will use magnetic resonance imaging (MRI) and olfactory stimuli to better understand the connection between sleep deprivation, brain activity, and olfaction in humans.
This study is aimed at testing the hypothesis that adaptive stimulation of the Subthalamic Nucleus (STN) drives changes in sleep episode maintenance and improves sleep quality. Investigators will directly test the efficacy of an adaptive stimulation protocol. Study subjects are adults with Parkinson's disease who experience inadequate motor symptom relief, and who have been offered implantation of a deep brain stimulator system targeting STN for the treatment of motor symptoms (standard-of-care). Investigators will implant 20 (n = 10 per clinical site) Parkinson's Disease subjects with the Medtronic RC+S System, enabling the implementation of real-time adaptive stimulation during in-home sleep. Prior to surgery, study subjects will complete clinical sleep questionnaires in an outpatient setting and wear an actigraphy watch for 3 weeks to monitor sleep architecture and sleep fragmentation. Three months after subjects have completed their standard-of-care Deep Brain Stimulation surgery and are optimized in terms of Parkinson's medication and clinical DBS stimulation parameters, we will monitor sleep for an additional 3 weeks, using in-home monitoring. During each week of the in-home monitoring period, subjects will undergo, in a randomized and double-blind fashion, one of three nocturnal stimulation algorithms: Adaptive stimulation, Open-Loop stimulation (standard clinical stimulation therapy) and No stimulation (control). During the 3 weeks of in-home sleep monitoring, we will monitor sleep architecture and sleep fragmentation using an actigraphy watch and subjects will complete a sleep questionnaire. At the end of the 3-week period of sleep-time randomized, blinded stimulation delivery, subjects will return to their standard stimulation therapy.
Currently, the investigators know that there is a high and increasing prevalence of sleep quality and quantity deficits in the general population with the social and health consequences that this entails. There are numerous activity wristbands linked to mobile apps that analyze sleep, but none can generate individualized recommendations for improvement interacting with the person. The main objective of the current project is to develop a virtual and interactive sleep assistant to increase the quantity and quality of sleep. Secondary objectives being the improvement of daytime sleepiness and the quality of life of the persons. Methodology: 202 participants in active employment who meet the criteria of "poor sleepers" (defined by a Pittsburg test score >5) are divided into 2 study groups. 1. Intervention group: Sleep data will be collected using validated questionnaires (SATED and the Sleep Hygiene Index) and objectively employing an activity bracelet, in which weekly, through a live chat, the medical staff of the sleep units will offer recommendations for the improvement of the deficits detected. 2. Control group: Same protocol as the intervention group, but the participants will not receive the recommendations via the interactive chat.
This study aims to investigate the effect of a 15-minute meditation practice on sleep architecture and high-frequency Heart Rate Variability (HF-HRV), as well as cognitive performance after both a well-rested and sleep-deprived night.
